Definitions

  • the present invention relates to a two-pack hair cosmetic material which is excellent in applicability to the hair and is reduced in the irritating smell due to ammonia.
  • a two-pack hair cosmetic material comprises a first agent containing an alkali agent such as ethanolamine, a carbonate and ammonia, and a second agent containing an oxidizing agent such as hydrogen peroxide. Both the agents are mixed together immediately before use to give a hair cosmetic material, and the hair cosmetic material is applied to the hair to bleach or dye the hair.
  • an alkali agent such as ethanolamine, a carbonate and ammonia
  • an oxidizing agent such as hydrogen peroxide
  • ethanolamine may have defects such as hair damage and skin irritation since it is very persistent on the hair. Further, since a carbonate is weak in the effect of enhancing bleaching power or hair dyeing power due to hydrogen peroxide, bright coloration of the hair may become insufficient. To the contrary, since ammonia does not remain in the hair, and further can sufficiently enhance bleaching power or dyeing power due to hydrogen peroxide, it is most generally used in a two-pack hair cosmetic material for bleaching or dyeing.
  • ammonia may emit a peculiar irritating smell that gives discomfort to a user when a first agent and a second agent are mixed together, or when a hair cosmetic material obtained by mixing both the agents together is applied to the hair.
  • a more overpowering irritating smell may be emitted to give discomfort to the user.
  • Patent Documents 1 and 2 a composition which reduces an irritating smell due to ammonia is known, which is obtained by incorporating an alkali agent into a liquid crystal structure of a hair cosmetic material.

  • the prepared first agent and second agent were sufficiently mixed together using a brush at a weight ratio of 1 : 2 at room temperature immediately before use until unevenness disappeared, and thereby, a sample was obtained. While each sample was further mixed using a brush a few times for evaluation, an irritating smell due to ammonia was evaluated sensory.
  • each 40 g and 80 g of the prepared first agent and second agent were placed, the bottle was closed with a lid, and the container was shaken up and down about 30 times to mix the first agent and the second agent together.
